With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.
AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel.
AISI 4140 steel grade is a versatile steel grade. 4140 material is widely used in a lots of industrial fields. It is a chromium-molybdenum alloy steel. It is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength.
AISI 4140 Alloy Steel is chromium, molybdenum, and manganese containing low alloy steel. It has high fatigue strength, toughness, abrasion resistance, and torsional strength. AISI 4140 is 1% chromium molybdenum medium harden the capability basic cause excessive tensile metal.
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Forging of this steel should be carried out between 2200 and 1650 F (1200 and 900 C). This alloy finds many applications for the aerospace and oil and gas industries, along with uses the automotive, agricultural and defense industries
AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications.
4140 high tensile steel 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved
AISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.
Welding 303 free machining stainless is tricky. When welding 303 to itself, I have found 308L to be the best choice, but for welding 4140 to 303 stainless, 309 stainless, 312 stainless, or hastelloy W are all good choices. Since hastelloy W has become so expensive, 309 stainless filler was used to weld the 4130 to 303.
4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.

AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.
4140 steel is chromium, molybdenum, manganese steel with good toughness, impact resistance and fatigue strength.1045 has slightly increased tensile strength and yield strength numbers than 1045 as a result of a slightly higher carbon content. Also, as a result of higher carbon content, 1045 is not as easy to weld as 4140.
Hi guys, Can anyone comment on weldability of carbon steel AISI 1045 & low alloy steel AISI 4140. Welding staff around me state that weldability of 4140 is better then 1045. Thus, in material selection during design they always go for 4140. They say, the grain size of 1045 is bigger than grain size of 4140 and that is what causing lower best aisi 4140
4140 is very nice to machine and the pre-hardened version is a real winner for surface finish. Try 400 fpm for roughing, .020" feed and as big a DOC as you have horsepower for. I was doing .19" DOC in a 3" diameter pre-hardened bar while testing a new Iscar tool (.032 nose rad) and that was about the limit for my 10hp spindle.

AISI 4140 steel also can be called DIN 1.7225 and JIS SCM440 steel. 4140 alloy steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness.
AISI 4140 is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28-32HRC.
4140 Alloy Steel Flat is an cold drawn annealed steel of relatively high hardenability with its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. 4140 Alloy Steel Flat responds well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 Alloy Steel Flat has good strength and wear resistance best aisi 4140
4140 steel is a high-strength alloy that is made up of iron, chromium, silicon and molybdenum. This material has excellent strength for lower weights. Heat treatment is a process of using high temperatures to change the molecular structure of the material in order to harden or soften the material.
4140 Alloy Steel Data Sheet. 4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140. 4140 HT is supplied in many forms such best aisi 4140
